Yes, teeth move throughout your lifetime.
Even though you may not notice it, your teeth are constantly shifting. This movement continues even after orthodontic treatments like braces. The primary reason for this subtle but continuous movement is the changing structure of your jaw as you age. According to provided information, "Though you can't see it happening, your teeth are always on the move. Even after you've had braces or other dental work, your teeth will continue to shift ever so slightly throughout your life. This movement is due to several factors, including: the changing shape of your jaw as you get older."
Here's a breakdown of why teeth move:
- Changing Jaw Shape: As you age, your jawbone's density and shape change, impacting tooth alignment.
- Natural Shifting: Teeth can naturally drift over time, filling in small gaps or responding to pressure from chewing and other oral habits.
- Post-Orthodontic Movement: Even after braces, teeth can gradually move back towards their original positions if retainers are not worn consistently.
